IMPROVEMENT IN LlFTlNG-TONGS.

Specification forming part of Letters Patent No. 19 0,19 1, dated May 1,1877; application filed I April 2, 1877.

. To all whom it may concern:

Be it known that I, JOHN T. CAMPBELL, of

Rockville, in the county of Parke and State of Indiana, have invented anew and useful Improvement in Lifting-Tongs, of which the following is aspecification:

Figure l is a side View of my improved lifting-tongs. Fig. 2 showsanother adjustment of the same.

Similar letters of reference indicate corresponding parts. The object ofthis invention is to furnish an improved device for lifting, carrying,dragging, or otherwise handling logs, timber, lumber, railroad-ties,stone, 8tc., and which shall be so constructed that it may be readilyadjusted, as the character of the work to be done may require.

The invention consists in a lifting-tongs in which the handles areconnected with the shanks of thejaws with an adjustable and reversiblejoint; and in the combination of the jaws, having their shanks bentoutward upon a true curve, the handles, having their inner ends bentupon the same curve as the shanks of the said jaws, the loops or hands,and the set-screws, with each other, as herematter fully described.

A are the grab-jaws of the tongs, the ends 01" which are curved inwardinto suitable shape for grasping the object to be handled. The jaws Across and are pivoted to each other, and their upper ends or shanks arecurved outward, or from each other, upon a true curve. B are thehandles, the inner ends of which are curved outward upon the same curveas the shanks of the jaws A, and the outer ends of which have hooksformed upon them. To the curved inner parts of the haudles B areattached loops or bands 0, of such a size and shape as to fit accuratelyupon the curved shanks of the jaws A. To one of the loops 0 of eachhandle B is applied a setscrew, D, to secure the said handles in placewhen adjusted. With this construction the handles B may be adjusted neareach other, as shown in Fig. 1, for dragging an object by a horsehitched to said handles, or by a single man, and may be adjusted out orin, according to the size of the object to be handled; or the handlesmay be reversed, as shown in Fig. 2, for two men to use in handlingobjects, and may be moved out or in, as the size of the object to behandled may require.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A lifting-tongs in which the handles B areconnected with the shanks of the jaws A with an adjustable andreversible joint, substantially as herein shown and described.

2. The combination of the jaws A, having their shanks bent outward upona true curve,

the handles B, having their inner ends bent upon the same curve as theshanks of said jaws A, the loops or bands 0, and the set screws D, witheach other, substantially as herein shown and described.
